Atrial tachycardia and other ectopic atrial rhythms occur when a site outside of the sinus node, but within the atria, creates action potentials faster than the sinus node. This ectopic focus ...

Wandering atrial pacemaker occurs when multiple areas (ectopic foci) within the atrium generate consecutive action potentials that are all conducted to the ventricles. Thus, each QRS complex will ...

It causes late potentials, which might have predisposed these patients to ventricular ectopy. However, their predominant problem is heart block with Stokes-Adams attacks, rather than cardiac ...

In this review, the authors discuss the role of ECG in prediction of stroke. ECG plays an important role in detection of several stroke risk factors/predictors including atrial fibrillation and ...

For ventricular ectopy, an instantaneous rate of >40–50 ... if the risk for potential aggravating cardiac effects due to the experimental conditions or suspected cardiac toxicity has been ...
